Subject [jira] Commented: (HBASE-1634) UI and shell list throw NPE
Date Tue, 14 Jul 2009 04:25:15 GMT

    [ https://issues.apache.org/jira/browse/HBASE-1634?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12730681#action_12730681

Haijun Cao commented on HBASE-1634:
-----------------------------------

I am on TRUNK. I don't think I have 1638 condition.


BTW, after "fixing" the UI, I try to count TestTable using hbase shell.  The count can't pass
region TestTable,0001100543. I scan the content of .META. table and notice that there is a
row that contains only "historian"? I am new to hbase (about 3 days old), so I really don't
know what all this means. 

Just wondering, to recover from this, can I manually delete all "TestTable,0001192603" entries
from .META. table? So that it does not stuck there? Is it safe? Thanks!

> I have a .META. from bryan duxbury that has a row with only historian data.  List does
whole row, not just info, so if only historian entries, a row is returned.  We then try and
get a regioninfo from this row and NPE.
> As to why this happens, jd suggests that since we moved to async historian updates, row
may have been deleted already.  Confirm.
